Here’s a very solar-centric home from Spain that not only has an entirely (485 square foot) solar roof that moves in relation to the sun all day to squeeze out every last possible carbon neutral electron but even the walls are solar power stations churning out even more electricity too. I hope it doesn’t buzz inside like a transformer! I’m a huge fan of solar powered zero carbon dwellings, but even I think this is possibly going a bit far. It literally would be a power station.
